Elasto-Plastic Analysis of a Non-Homogeneous Solid Media Using Linearly Conforming Radial Point Interpolation Method

In this paper a non-homogeneous solid medium is analyzed by a truly mesh-free method. In this method the geometry of solid structure is simulated by distributed nodes and the displacement field in the domain is constructed by enriched radial point interpolation method. Nodal integration is used to get rid of the dependency of the mesh-free method to the background mesh. The non-homogeneity of solid media is simulated by assigning different material properties to each node. The accuracy and efficiency of proposed method is investigated by solving some examples at the end of the paper.
